Hi!
As mentioned earlier, the vectorizer punts on vectorization of loops with
non-constant
steps. As for OpenMP loops it is by the language restriction always possible
to compute
the number of loop iterations before the loop, this change helps those cases
by computing it and using an alternate
Hi,
this patchs finishes the parameter tracking by implementing the iterative
dataflow in propagation stage. This is necessary since we now can
propagate how the pointers are passed around recursive calls (as done in
a testcase) and thus it is no-longer safe to simply merge all summaries
in one SCC

What's the use case for that? IIUC board flags are supposed to be ones
that are absolutely required f
The code that collect2 generates, compiles and links into applications
and shared libraries to initialize constructors and register DWARF tables
is built with the compiler options used to invoke the linker. If the

Found when looking at PR97203 (but having no effect there).
The GCC ME optimizes with -O1 (or higher) the
a = sinf(x)
b = cosf(x)

(...i as in internal; like cexp(z) but with with __real__ z == 0)
In expand_builtin_cexpi, that is handles as:

Glibc 2.32 adds a global variable that says whether the process is
single-threaded. We can use this to decide whether to elide atomic
operations, as a more precise and reliable indicator than
__gthread_active_p.
This means that guard variables for statics and reference counting in
shared_ptr can u
